3 x 3 Pixel Convolver (Mode 10)
This filter configuration accepts a 3 pixel-square neighbor-
hood, side-loaded three pixels at a time through input ports
A, B and C, and multiplies the 9 most recent pixel values by
the coefficient set currently stored in the registers. These
products are summed with the data presented to the cascade
input, and a new 3-cycle impulse response, rounded to 16
bits, is available at the output port 5 to 7 clocks later, with a
new output available on every clock cycle.
The input pixel data are automatically shifted one location to
the right through the three rows of multiplier input registers
on every clock in anticipation of three new input data words,
effectively sliding the convolutional window over one col-
umn in an image plane.
